usb: udc: remove warning when queue disabled ep
In the Linux kernel, the following vulnerability has been resolved: usb: udc: remove warning when queue disabled ep It is possible trigger below warning message from mass storage function, WARNING: CPU: 6 PID: 3839 at drivers/usb/gadget/udc/core.c:294 usb_ep_queue+0x7c/0x104 pc : usb_ep_queue+0x7c/0x104 lr : fsg_main_thread+0x494/0x1b3c Root cause is mass storage function try to queue request from main thread, but other thread may already disable ep when function disable. As there is no function failure in the driver, in order to avoid effort to fix warning, change WARN_ON_ONCE() in usb_ep_queue() to pr_debug().

Exploit status
No known public exploit
No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.
Research context
For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.
Timeline
From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.
No dated events beyond publication.
FIRST EPSS daily score; only changes of 0.01 or more are recorded (step chart).
Patch and commit links
Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.
No commit or PR link among the references.
Credits
All researchersFinders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.
No credits in the CNA record.
Variant candidates
Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
No nightly-computed relations.
Chain candidates
An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
